In order to determine the optimum technological parameters of dry anaerobic fermentation of sugarcane leaves, an orthogonal experiment was conducted with method of composting, grass-manure ratio and fermentation temperature as three key factors in the experiment. The maximum gas yield of 655.30 L was obtained with natural composting at optimum grass-manure ratio of 1 and optimum fermentation temperature of 38℃. The results also showed that pig manure had a great impact on the dry anaerobic fermentation of sugarcane leaves. When the amount of manure was relatively small, the increasing of the fermentation temperature could also improve the gas production. The adding of two agents, Green Straw Decomposition and Stalk Rot Agent, had no effect on fermentation of sugarcane leaves in composting. 
